(failure to recruit)
Primary outcome measures are: 1) The time elapsed between the start of grasp (when the finger breaks contact with the thumb) and the start of transport (when the wrist leaves the start position); and 2) The time elapsed between maximum aperture of the hand and peak deceleration of the wrist. Secondary outcome measures are: 1) movement duration, 2) time of maximum aperture expressed as % of movement duration, 3) time of peak deceleration expressed as % of movement duration, 4) amplitude of peak velocity of the wrist, 5) time of peak velocity, 6) time of peak velocity of the wrist expressed as % movement duration, 7) size of maximum aperture, 8) time to close hand from time of maximum aperture, 9) distance to target at time of maximum aperture.
